Threads like this one, help us all so very much. Though I've had mt 67 since early 78, I've never known there was not supposed to be a seam there and would nave just put any supplied vinyl roof on again. My original roof had already been peeled off before I got the car. The roof was bare factory primer-sealer with a rough glue texture at the time. I already knew about the brad nails (as Jeff called them) and I knew about the riveted drip rail steel strip.Underneath and around these items I discovered the original color of my roof was white (confirmed finally with a Marti Report earlier this year) My example has a chrome strip that is over that riveted steel strip. I have seen other examples of 67's (and 68's) that had a vinyl roof but didn't have these items and no evidence (holes not present for the riveted strips) they came with these strips. I have rarely seen other examples that had these rivets or strips on them (though the southern California scene I lived in while identifying examples didn't really like vinyl roof too much because they sun-rotted too fast in that climate)
Maybe some clarity can be established here on different examples. Some may have been dealer or PO installed, I am sure. I understand from another thread, that the roof sail panels were not finished the same when leading the quarter panel to the roof panel, so the factory trim molding doesn't fit correctly on cars not intended to have a vinyl roof (on assembly line).
